实际上,如果看open3d的Surface Reconstruction, open3d 是自带Alpha Shapesimplementation,并且改变不同的 alpha,会得到不同的形状。 alpha = 1 (真的非常凸包): alpha = 0.3: 其实我感觉在这个 case, alpha = 0.3, 有略微捕捉一些细节,但整体提升就还好。 open3d a
A Python package for reconstructing the shape of a 2D point cloud on the plane. Introduction Given a finite set of points (or point cloud) in the Euclidean plane, alpha shapes are members of a family of closed polygons on the 2D plane associated with the shape of this point cloud. Each...
为了匹配目标形状的一般结构，弯曲源形状同时保留源的表面细节，本文提出了一种形状变形后的保护细节的方法。该方法将源形状由一个粗调的控制网格(称为保持架)包围，并且通过特殊的权重函数将指定的保持架顶点的粗调到源网格上的任意点，从而扩展了传统的基于网格的变形技术。使用这种稀疏的保持架结构，无论形状和拓扑...

billion tokens at 4096. We found that sequence length warmup (Li et al., 2022) helped stabilize early spikes during the first ~80 billion tokens of pre-training. However, it was not applied to the final runs due to significant throughput penalties as length shapes grew across the curriculum...
